Abstract
The utility model discloses an automatic opening and closing device for the dustproof covers of illuminating lamps, which is suitable for automatically protecting the transparent glass of the illuminating lamps, which belongs to the mechanical control device of adopting an electromagnetic technology. The utility model is characterized in that a tractive electromagnet is arranged and is connected with a lever whose one end is provided with a bobweight iron through a draw rod, the other end of the lever is connected with the dustproof cover of a lamp surface into a whole, a hinge point is arranged between the dustproof cover and the shell of a lamp, and an electromagnet coil and the bulb of the lamp are simultaneously switched on and off. When the lamp is illuminated or extinguished, the dustproof cover rotates around the hinge point for automatically opening or closing. The utility model realizes that the dustproof cover is illuminated or extinguished along with the lamp for automatically opening or closing, solves the protective problem of an illuminating lamp in a tunnel and has the advantages of convenient management without people, simple structure and low cost.
Description
This lighting dust cap automatic switch device is applicable to the transparent glass of protection lighting, is particularly suited for protecting lighting in the tunnel, makes it avoid oil smoke, contamination by dust or artificial the damage, belongs to the machine control unit that adopts electromagnetic technique.
The light transmission glass plate of railway tunnel lighting, in use its surperficial Chang Yin is reduced transparency by dust, oil pollution, sometimes also can be by the people for smashing, influence is used.
The purpose of this utility model be exactly to design a kind ofly can open automatically, the device of closure of a tunnel lighting dust cap; this device can make the dust cap that is connected on the lighting open or close along with lighting or turn-offing of light fixture; thereby promptly do not influence the normal use of light fixture, can protect the light transmission glass plate of light fixture again.
The purpose of this utility model can realize in the following manner.Tractive magnet is set, lamp face dust cap and installing plate thereof, an end has the lever of balance weight iron; Tractive magnet is connected with lever through pull bar, lever one end has balance weight iron, the other end and lamp face dust cap combine as a whole, lamp face dust cap is connected on the installing plate, installing plate is fixed on the luminaire housings, be connected with twisted point between lamp face dust cap and the luminaire housings, through this twisted point lamp face dust cap can upper and lower turn to position closely connected with light fixture lamp face or that open; The magnet exciting coil of tractive magnet is connected in the light fixture lamp circuit, with the synchronous switching power supply of the lighting that is protected.
The utility model has the advantages that lamp face dust cap along with the power supply switching, lighting, extinguishing of light fixture and open synchronously or shut promptly do not influence the normal use of light fixture, protected light fixture lamp face not to be damaged at ordinary times again; Utilize electromagnetic principle and lever principle to realize the automatic switch of dust cap, be convenient to unattended; Balance weight iron, pull bar can be selected, adjust, and make this device can adapt to various model light fixtures.
Below in conjunction with drawings and Examples the utility model is done into one not illustrate.
Fig. 1 is the utility model structure cutaway view;
Fig. 2 is that lamp face dust cap is installed the A view;
Fig. 3 is the utility model operating principle schematic diagram;
Fig. 4 is a tractive magnet coil magnetization circuit diagram among the embodiment.
Among the figure: 1-luminaire housings, 2-tractive magnet, 3-pull bar, 4-lamp face dust cap, 5-installing plate, the 6-balance weight iron, 7-adjustment screw, 8-light fixture lamp face, 9-lever, 10-twisted point, the 11-rotating shaft, the 12-magnet exciting coil, 13-armature, the B-C camber line is the angle that lamp face dust cap is opened among Fig. 1.
In the present embodiment, balance weight iron 6 is the counterweight iron staff, and the weight of its weight and lamp face dust cap 4 adapts; The fulcrum of lever 9 is located in the rotating shaft 11 of twisted point 10; Pull bar 3 is the adjustable length integral expression, and its length and lamp face dust cap 4 leave the angle that light fixture lamp face 8 opened and adapt.
The magnet exciting coil 12 of tractive magnet 2 is connected in parallel in the load circuit of light fixture lamp circuit.Tractive magnet 2 is a vertical type, its armature 13 lower end cylinder lever connecting rods 3.When the power connection light fixture is lighted simultaneously; the magnet exciting coil 12 of tractive magnet 2 has; when armature 13 upwards picks up; pull bar 3 operating levers 9 that are attached thereto drive lamp face dust cap 4 and are rotated down around hinge 10; make dust cap 4 be in full open position; otherwise; work as dump; illuminating lamp is in off working state; also dead electricity of tractive magnet 2 simultaneously under the effect of the lever 9 that lamp face dust cap 4 combines as a whole at the gravity of counterweight iron staff 6 and with dust cap 4, rotates up around hinge 10; make dust cap 4 be positioned at the position mutually closely connected, with the light transmission glass plate (referring to Fig. 3) of protection light fixture lamp face with light fixture lamp face 8.Realize that thus lamp face dust cap 4 opens automatically, cuts out along with lighting, extinguishing of light fixture.
